rATENr SASI-I-LOGK.

To allwhomitmayconcern." f ,Beit known that'I, JAMns 0. LONG, a

bitizen of the United States, residing at Cedar Rapids, in the county ofLinn and :State of Iowa, have: invented certain new andusefullmprovements in Sash-Locks;

and I dohere'by declare the following to be latch; for automaticallymoving into *a* keeper, for locking the window sashes-when they aremoved into a closed position.

Another object of this invention is to provide a window look asspecified, which includes a supporting plate, having a housingdetachably mounted thereupon, in which is slidably mounted the lockinglatch, and further to provide a locking latch which is composed of alocking head having a reduced shank extending therefrom, Which shank isremovably seated in a pulling member for unlocking the look, when it isdesired to open the window.

A still further object of this invention is to provide an automaticacting sash lock, which is comparatively simple in construc tion, easyto manufacture, and which is du rable, the parts being interchangeable,upon the wearing out of any one of'the parts of the lock.

With the foregoing and other objects in view this invention consists insuch novel features of construction, combination and arrangement ofparts as will be hereinafter more fully described, illustrated in theaccompanying drawings and claimed.

In describing the invention in detail reference will be had to theaccompanying drawings wherein like characters designate like andcorresponding parts throughout th several views, and in which a Figure 1is a fragmentary section of a window, showing the lock applied thereto,

Fig. 2 is a plan view of the lock, showing the housing removed, 7

Specification of Letters Patent. Patented 20, 19 9- i ig. 5 isa-perspective view of the latch pu l.

Fig. 6 is a perspective view-of a housing.

Referring more particularly to the drawings, .1 and 2 designate windowsashes of'ordinary construction, which have mid rails 3 and 4. The midrail 4' of the lower sash 2,

has a: metallic plate 5 secured thereto, by screws or analogousfastening devices, illustrated at 6.v The plate 5 is vprovidedx'with anupstanding tongue 7 formed centrally of its I ends, upon its rearOrouter edge. A shank 8 extends through a centrallyxdisposed openingformed in the tongue '7. The shank 8 is formed upon and extendsoutwardly from a latch head-.9, of ordinary shape, having one end 10tapered. The shank 8 has its outer end externallyLscreW. threaded, as isshown .-at 11, for detachable connection with a pull member 12. The pullmember 12 is positioned upon the opposite side of the tongue 7 from thehead 9, and it has an upstanding curved finger engaging plate 14 formedupon its rear end. The plate 14 curves outwardly, so as to provide aconcave surface for engagement with a finger of the operator of thelatch. A spiral spring 15 is coiled about the shank 8, between the inneror butt end of the head 9, and. the inner surface of the tongue 7, andit tends to force the latch head 9 outwardly.

The plate 5 is provided with a plurality of spaced slots 16 extendingtherethrough upon each side of the head 9. The slots 16 are provided forreceiving the tongues 17 which are formed upon the housing 18, forproperly positioning the housing for inclosing the shank 8, spiralspring 15 and a portion of the head 9. The housing 18 has laterallyextending wings 20 formed thereupon which engage the upper surface ofthe plate 5, and are secured to the plate, by the screws or analogousfastening means 6, by means of which the plate is attached to the midrail 4 of the lower sash 2 of the window.

The mid rail 3 of the upper sash 1 has a keeper of ordinary constructionmounted thereon, for receivingthe latch head 9, for locking the windowsashes in a closed position.

When the sashes 1 and 2 are closed, the spring 15 will force the latchhead 9 into the keeper 21 which is carried by the mid rail 4, andautomatically lock the window. For unlocking the window, reparatory toopening the same, the latch 9 is moved eat Brion.

of the keeper 21, by pulling upon the pull member 12, which movesthelatch head 9 out of the keeper 21, against the tension of'the spring15.

In reducing the invention to practice, certain minor features ofconstruction, combination, and arrangement of parts may necessitatealteration, to which the patentee is entitled, provided such alterationsare comprehended within the scope of what is claimed.

What is claimed is A sash lock comprising a plate having a pair ofspaced apertures and pairs of spaced slots located in a plane within theapertures, a housing located on the plate and having each end open,tongues formed on the lower side edges of the housing and extendingthrough the slots and bent at right angles to underlie the plate forsecuring the housing to the plate, a pair of oppositely disposed flapsformed on the side edges of the housing and having apertures'inregistration with said apertures of the plate, fastening -elementsextending through the aperslidahle in said opening, a latch head securedto the forward end of said shank and partially covered by said housingwhen in its normal position, a spring engaging the head and last namedtongue for urging the head outwardly of the housing, a cylindricalmember threaded to the'outer end of the shank and engaging the lastnamedtongue to limit the outward movement of the head fromthe housingand capable of adjustment on the shank to adjust the tension'of thespring,

and a finger grip on the cylindricalmember.

In testimony whereof I afiix my signature in presence of two witnesses.
